ARB工艺对1060工业纯铝组织和性能的影响 王超1,袁守谦1,张西峰1,张兵1,吕爽1 (1.西安建筑科技大学材料科学与工程学院,陕西,西安,710055) 摘要:采用ARB技术中两种轧制工艺, 研究变形后1060工业纯铝的显微组织和力学性能变化. 结果显示, 在两种ARB轧制工艺中, 单向轧制工艺的晶粒细化效果明显好于换向轧制. ARB7道次后, 采用单向轧制工艺试样的显微组织由拉长的细小纤维状晶粒组成, 平均晶粒尺寸是470 nm;采用换向轧制工艺试样由等轴状晶粒组成, 平均晶粒尺寸是680 nm. 同时, 单向轧制后, 材料的抗拉强度和显微硬度提高程度大于换向轧制, 但延伸率却不如换向轧制. 分析了ARB过程材料的变形规律和细小晶粒的形成机制. 关键词:累积复合轧制; 1060工业纯铝; 轧制工艺; 显微组织; 力学性能; [全文内容正在添加中] ......
